OBJECTIVE: To compare the effectiveness of paper-patch, fat, and perichondrium myringoplasty in the treatment of chronic tympanic membrane perforations smaller than 3 mm. SUBJECTS AND METHODS: This investigation included 45 patients with chronic tympanic membrane perforations smaller than 3 mm. The patients were equally divided into 3 main groups according to surgical procedures. Each group consisted of 3 subgroups, which had 1-mm, 2-mm, and 3-mm perforations. The patients underwent paper-patch, fat, or perichondrium myringoplasty via transcanal approach under local anesthesia. Healing of perforation, hearing improvement, and complications were investigated. RESULTS: Closure rates of the perforations in the paper-patch, fat, and perichondrium myringoplasty groups were 66.7%, 86.7%, and 86.7%, respectively. There were no statistically significant differences in tympanic membrane closure rates between techniques with regard to size. CONCLUSION: Three techniques were found to be feasible for tympanic membrane perforations smaller than 3 mm. 相似文献

Relationship between bone mineral density and biochemical markers of bone turnover in hemodialysis patients 总被引:1,自引:0,他引:1
End-stage renal disease is closely associated with changes in bone and mineral metabolism. In recent times, osteoporosis has become important among hemodialysis (HD) patients. In this study, the investigators sought to evaluate the relationship between bone mineral density (BMD) and biochemical markers of bone turnover among HD patients. A total of 70 uremic patients on a maintenance HD program for at least 1 y were enrolled in the study. All patients were treated with conventional bicarbonated HD for 5 h through the use of low-flux hollow-fiber dialyzers. Bone densitometry was measured by dual energy x-ray absorptiometry in the lumbar spine (LS) and the femoral neck (FN). BMD was classified according to World Health Organization criteria on the basis of BMD T scores. Biochemical bone turnover markers such as calcium, phosphorus, ionized calcium, intact parathyroid hormone, alkaline phosphatase, plasma bicarbonate, blood pH, serum albumin, and hematocrit levels were measured before the HD session in the morning. Male patients (n=37; 52.9%; mean age, 46.2+/-17.0 y) were assigned to a single study group, and female patients (n=33; 47.1%; mean age, 44.0+/-13.1 y) to another. Mean duration of HD treatment was 33.7+/-28.5 mo in females and 33.0+/-26.0 mo in males. Among all patients, BMD T scores in the osteopenia/osteoporosis range were observed at the LS in 58 patients (82.8%) and at the FN in 45 patients (64.3%). According to BMD measurements in FN T score, 10% of patients (n=7) were osteoporotic, 54.3% (n=38), osteopenic, and 35.7% (n=25), normal. On the other hand, in LS T score, the results were 47.1% (n=33) osteoporotic, 35.7% (n=25), osteopenic, and 17.1% (n=12), normal. No statistically significant association was found in osteopenia/osteoporosis between sexes according to FN and LS T score (P=.542, P=.267, respectively). No significant relationship was noted between BMD and biochemical markers of bone turnover. A positive correlation was found between FN T scores of BMD and age (r=.413, P=.000). BMD T scores within the range of scores for osteopenia/osteoporosis were observed in 78.5% of patients at the LS and in 58.5% of patients at the FN. The investigators concluded that no correlation could be found between markers of bone turnover and bone mass measurements in both skeletal regions. LS T score results were worse than FN T score results. Elevated alkaline phosphastase levels combined with high intact parathyroid hormone levels are predictive of renal osteodystrophy but not of adynamic bone disease/osteoporosis. 相似文献

Objective
The aim of this study was to analyze the risk factors contributing to the misdiagnosis of perilunate injuries.Methods
The study included patients who had perilunate dislocation or fracture dislocation correctly or incorrectly diagnosed on initial examination between 2008 and 2014. Data related to the length of time until correct diagnosis of the perilunate injury; cause of injury; presence of associated fractures, polytrauma or concomitant trauma in the ipsilateral upper extremity; time between injury and first presentation; first treatment applied; presence of ligamentous perilunar injuries only or fracture and dislocation; inadequate radiographic assessment; and experience of the physicians were recorded and analyzed.Results
A total of 44 wrists were included in the study. Of those, 10 (22.7%) wrists (mean patient age: 44.4 years [28 ± 58 years]) with perilunate injuries were misdiagnosed in the initial evaluation. All of the risk factors were found to be similar between the group of patients with correct initial diagnosis and missed diagnosis group, except for the experience of the orthopedic surgeon assessing the injury (p = 0.0001). Of the surgeons who missed the diagnosis, 70% reported that it was their first encounter with a perilunate injury.Conclusion
The results of this study indicated that lack of experience was the most important factor in the misdiagnosis of perilunate fracture dislocation or isolated dislocation. Level of Evidence: Level IV, diagnostic study. 相似文献84.
We aimed to study the relation between sex hormones and depression among elderly women. The study was carried out on 74 volunteered female subjects above 60 years of age. Each subject was asked to fulfill the geriatric depression scale (GDS) questionnaire and further evaluated for clinical depression by a psychiatrist using the DSM IV diagnostic criteria. For statistical analysis, subjects were later divided in two groups, according to the presence of clinical depression. Cognitive functions were assessed with the standardized mini mental test (SMMT). Disability in the activities of daily living was assessed with instrumental activities of daily living (IADL) scale. Plasma levels of estrogen, testosterone, progesterone, and dehydroepiandrosterone sulfate (DHEA-S) were measured with chemiluminescent methods, and plasma levels of androstenedione were measured with radioimmunoassay. Among 74 subjects, 34 (39%) had clinical depression. Age, number of years spent in education, SMMT scores, and IADL scores did not differ between the depressive and non-depressive groups. Plasma sex hormone levels were not found to be different between the two groups. 相似文献

In our experimental study, the aim was to recover vocal cord physiology in cutting of recurrent laryngeal nerve, thus phrenic-recurrent
nerve transposition was planned in rabbits. Experiments were performed on 10 experimental and 10 control rabbits. The right
recurrent nerve was cut in the control group, while in the experiment group, the right recurrent nerve was cut. Then, a right
phrenic-recurrent nerve end-to-end anastomosis was performed and the results were evaluated. After the 3rd postoperative week,
videolaryngoscopy (VLS) and intramuscular electromyography (EMG) could not be evaluated in 1 rabbit from the experimental
group which had died during anesthesia. In eight of the nine rabbits in the experiment which underwent VLS and EMG, activity
was recorded in the right vocal cords. On light microscopic examination, atrophy was not detected in the vocal cord muscles
of 9 rabbits among the 10 in the experiment group, while all rabbits in the control group and 1 rabbit in the experiment group
were diagnosed with vocal cord atrophy. A success rate of approximately 90% was obtained based on the pathologic examination.
We believe that the method can be used in patients without any contraindications, considering the complications of tracheostomy
and the quality of life. 相似文献

This study was designed in order to investigate in vitro antioxidant potentials of 80% methanolic extracts prepared from three edible fruits, Cornus mas L., Diospyros kaki L., Laurocerasus officinalis Roem. For this purpose, 8 different tests were performed including 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide radical scavenging tests, ferric reducing antioxidant power (FRAP), cupric reducing antioxidant capacity (CUPRAC), metal-chelating capacity, determination of total antioxidant capacity, β-carotene bleaching test in a linoleic acid emulsion system and trolox equivalent antioxidant capacity. In addition, for evaluating the phenolic profile, total phenolic, flavonoid and proanthocyanidin contents were measured spectrophotometrically. Among the three fruits analyzed, Diospyros kaki L. showed the highest activity in all tests, except β-carotene bleaching test. Whereas, neither of three fruits showed metal-chelating activity. Also, a good correlation was found between the phenolic content and antioxidant parameters. 相似文献

Introduction The aim of the present study was to evaluate the effects of erythropoietin (EPO) on the histopathology of testes after unilateral
testicular torsion and detorsion.
Materials and methods Twenty-five male Sprague–Dawley rats weighing 120 g were used in this study. The rats were randomly divided into three groups,
a sham group consisting of five rats and the other two groups consisting of ten rats. In group 1 (sham group), right orchiectomy
with no additional intervention was performed. In group 2 (T/D group), torsion was created by rotating the testis 720° in
a clockwise direction for 4 h. After a 4-h torsion period, the right testis was detorted and replaced into the scrotum for
4 h. After the torsion, 0.5 cc 0.9% NaCl solution was injected once and three times in a week (total 12 doses). In group 3
(T/D + erythropoietin; EPO group), the same surgical procedure was done as in group 1, but EPO 1,000 IU/kg was injected just
before the detorsion and three times in a week. At the end of each procedure, bilateral orchiectomies were performed for the
histopathological examinations in all groups.
Results We examined the testes weight, vascularization of the region between the seminiferous tubules, percentage of necrotic seminipherous
tubules, and maturation of spermatogenesis in terms of necrosis, sertoli cells, maturation arrest of spermatogenesis, hypospermatogenesis,
and normal spermatogenesis of torsioned testis tissues with and without EPO treatment. Extremely significant differences in
testicular weight were observed in group 1 compared to groups 2 and 3 (P < 0.001).
Conclusion Administration of EPO significantly influenced the rescue of testicular function by preserving the intact seminiferous tubular
morphology, lowering the percentage of necrotic seminipherous tubules, and significantly reducing histological damage (P < 0.05). 相似文献
